Hint:There are basically two types of earth movements: rotation and revolution. The amount of time taken by Earth to complete one rotation is 24 hours approximately. Revolution is the motion of the earth around the sun.

Complete answer:
 The motion of the earth around its axis is termed as rotation. The Earth has an angle of 23.5 and is perpendicular as a result Earth is tilted on its axis. Seasonal changes on Earth occur as a result of this rotational tilt. The part of Earth tilted towards the sun experiences summer and the other tilted away from sun experiences winter.
Earth makes a complete rotation in approximately 24 hours that is referred to as earth day. Rotation of Earth is constant but its speed differs with latitudes. The speed decreases, as we move towards northern and southern poles. At poles, the speed is so slow that it takes an entire day to spin. The closer to the equator, the faster the Earth's rotation.
The circumference of the Earth at the equator is 40,000 km. Earth completes one rotation in 24 hours. One hour is equal to 60 min so 24 hours =24×60=1440 min
Speed of rotation =DistanceTime=40,0001440=27.7 approx.
So, the Earth rotates approximately 27.7 kilometres in one minute at the equator.

Note: The rotational speed of Earth at the equator is 27.7 km/min. As we move closer towards poles, its speed decreases. The seasonal variation and day and night phenomenon in the earth is due to deviations in the angle of inclination of the Earth.
